“The Mighty Sky is a shining example of the ways in which educators want to encourage people of all ages to think about and investigate the world around us in creative ways. By engaging us in the universe musically, Alvey, Chapman, and Roboff have helped us understand some ‘mighty’ physics and astronomy concepts in ways that help us to understand and have fun, at the same time!” ~ Vicki H.
